Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Sat Dec 03 2022 12:32:05 ACUS01 KWNS 031231 SWODY1 SPC AC 031230 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0630 AM CST Sat Dec 03 2022 Valid 031300Z - 041200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Severe thunderstorms are not expected today. ....Synopsis... A midlevel shortwave trough will move quickly eastward from the lower Great Lakes across New England today, to the south of a deep vortex near Hudson Bay, and north of a subtropical ridge over the Gulf of Mexico. A surface cold front will begin to slow its southeastward movement across the lower MS Valley, and the front will move offshore of the Mid-Atlantic this evening and eastern NC early tonight. Low-level moisture will remain greater toward the Gulf coast where forcing for ascent will slowly weaken with time along the slowing front, and midlevel buoyancy appears to already be diminishing farther north in advance of the front, from the southern Appalachians to VA. Overall, while isolated lightning flashes will be possible early today (primarily from LA to AL), the threat for thunderstorms is expected to largely diminish by later today. Otherwise, a few thunderstorms will be possible tonight near and just east of the NC Outer Banks as the cold front encounters a narrow corridor of increasing low-level moisture over the Gulf Stream. Farther west, a midlevel low will move slowly eastward toward northern CA, where there may be sufficient midlevel cooling for isolated/low-topped thunderstorms late tonight near the coast. ...Thompson/Gleason.. 12/03/2022 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
